Thisinvention relates to a method of gluing backs on to books and'tova machine for performing saidmethod Vand has for an ob# ject to provide a rapid, eilicient, simple and economical method and machine of 'the class described. I

Machines 'have been devised and are 4in use f for gluing backs on to catalogs, paper covered directories and other books but such machines y are -so large, complicated and expensive as Vto preclude theiruse inl small plants, whether' in largeor small communities ,'in which jobs requiring such work `are infrequent and it is the obj ect of the present invention to provide l5 both a new'afnd improved, simpleand efficient l method of gluing backs on to books and a machine for that purpose which shall be so small, simple and ,cheap that the profits from one or two ordinary catalog orgsimilar jobs will pay for the'installation of the machineA so that almost any small printshop can afford to have such a machine as a part of its equipment.

Because of the eliicienc-y of the method and machine hereinafter described and claimed, the luse thereof will not, however, beby any means limited to suchsmall shops.

The foregoing and other objects will more fully appear fromthe following specification '30 and claimV as illustratedin the accompanying drawings wherein like characters of reference n indicate corresponding parts throughout and in which v .Figure Iris a plan of the machine, ajportion 355 ofthe topV being broken away and certain parts being showninsection and other parts in dotted lines.V

their' backs in alignment 'and apply the glue by brush or other suitable means ,to the yplu- Y rality of the backs thus aligned, thereafter taking the booksone at a time and placing the glued back of the book into the covery aty the proper place. Thebooks must'be taken from such a pile while the glue is sufficiently moist to properly stick to the back of the book when applied. In this condition t-he glue is so stringy that when the books are separated the gluewill lstring, out and mess the job.

In many'cases the cover cannot be held to the book in a sufficiently secure manner by vapplyingtheglue simply at the 'back'edge of the book. Insuch cases it is a common expedient 65 to apply glued strips of cloth or the like to the 4book and the cover,V inside the cover and adjacent the back, and to thus reinforce the binding between the book and the cover. Ob-

viously such an'operation is cumbersome and 70 takes a considerable amount of time and expense both for materials and labor.

The presentnvention eliminates the objections above specified, as well as other objectionable features in lthe ,gluingl of covers on to booksacoording to present commonly employed methods and also generally simpliiiesfand cheapens the entire operation. 'f

They method constitutingl a part of the present invention comprises running thef' cover, while still flat, over a support and applying to the cover a streak cf glue of the desired width, passing the cover, in a'continuous process, to a carrier` arranged to keep the glued portion of the cover-from contact with anything else, and delivering` the covery from the carrier-to a table where the book is to be set in the cover, `one of thev vital partsA of the method being that the speed of movement and t-he length of the carrier are soarranged and adjusted that, considering the consistency of the glue used, the glue will,

` during its passage on the carrier while eX- posed to the air, dry to the proper consistency for immediate insertion vof the book in the 95 cover. By this method the operatio-n is made n continuousg'no gluedbooks or glued rcovers are permitted crrequired to be cared for and protected with regard to smearingthe glue or contacting with other objects and the W roper consistency of the glue is automatically provided for throughout the running of the job, subject only to the proper regulation, easily determined and accomplished by those skilled in the art, at the beginning of the job.

A further feature of the process is the provision yfor the reinforcement at the sides of the binding to eliminate the use of strips of cloth or other material as above referred to. In operating the method, where such a binde ing is required, the cover is first creased by any suitable machine or method in common use for such purposes, four creases being made in the cover as clearly illustrated at Fig. VI. The glue is thereafter applied to the cover in a strip, covering all the space between the two outer creases. The back of the book is positioned in the space between the two inner creases, and the sides of the cover are then pressed against the sides of the book whereby the glued strips on either side ofthe central strip will be attached to the sides of the book adjacent the back. The two inner creases mark the strip for the placing of the back of the book and also provide for the easyy and efficient bending of the back of the book at the edges of the back. The two outery creases form hinges for the opening of the sides of the book, these creases being at the edges of the glued strips which attach.

tothe sides of the book adjacent the back thereof. By this method a double reinforced glued back is provided without trouble, work or expense in addition to that required for the simple back-gluing of the cover, except the additional Work of creasing the covers. All work and expense incident to the usual operation of placing and gluing the cloth strips as above described is eliminated.

For the operation of this method and for the general simplification and cheapening and making more efficient the operation of gluing backs or covers to books, the present invention includes a machine for this purpose Y which will now be described.

A tank 1 supported on standards 2 is provided for holding water 3 to be heated by any suitable means as burner 4 positioned beneath the tank.

A glue pot 5 holding glue 6 is provided to be supported in the water tank in any suitable manner as by hooks 7 engaging the upper edges of partitions 8 in the tank 1. Handles 9 are provided for lifting the glue pot 5 from the tank when desired. By this construction the glue 6 may be kept at the temperature and consistency desired, by means of the partial immersion of the glue pot in the heated Water in the tank.

' A table top 10 with side fianges 11 is provided, having apertures 12 therein to permit rollers 13 to project upwardly therethrough for moving the work across the table top as hereafter described The top 10 is also provided with a cut-away 14 extending from a point back of the gluing wheel, hereinafter described, and continuing thence to the delivery edge of the top adjacent the carrier, as hereafter described.

A shaft 15 is revolubly mounted in the walls of the tank as at 16 and has mounted thereon rollers 13 projecting through the top 10, as hereinabove described. The rollers 13 areprotected from the water 3 by means of suitable semi-circular partitions 17 running from thewalls of the tank to the interior partitions 8.

A shaft 18 is mounted above and parallel to the shaft 15, by any suitable means as sup ports 19, and provided with suitable means as crank 20 for revolving the same, and carries rollers 21 attached to the shaft by screw col-y lars 22 and positioned opposite and lfor coaction with the rollers 13 and engaging the same whereby the revolution ofthe shaft 18 will, through the engagement of rollers 21 and 13, cause the shaft 15 to be revolved.

Guide rollers 23 are likewise attached to the shaft 18 by screw collars 24, the screw collars 22 and 24 permittingready adjust-- ment, longitudinally of the shaft 18 of the rollers 21 and 23. Y Y

Slots 25 may be provled for the accommodation of the work positioning slide 26 which is of common'construction and well understood by those skilled in the art and requires no further description.

rlhe gluing wheel assembly shown indetail in Fig. V is mounted upon the shaft 15 within the glue pot 5 and consists of a sleeve 27 provided with a. flange 28, the shaft 15 and the collar 27 being provided kwith a series of registering holes 29 to accommodate a pin 30, and the flange 28 and shaft 15 being provided with registering holes for the accommodation of the pin 3l.

The gluing wheel is formed of any suitable number of sections 32 adapted for slidable mounting on the collar 27 andfor retention thereon by the flange 28 on theone side and the pin on the other side of the section or sections constituting the wheel, it being understood that each of the sections is of a thickness corresponding to the space between the holes 29 whereby any number of sections may be added to vthe wheel and may be held in substantially compact or solid position as a single wheel on the collar 27 by means of the flange 28 on one sideofsaid sections and a pin 30 inserted through the hole 29 on the opposite side of the wheel thus formed.

Sections of thewheel not desired for use may be slid from the collar and hung upon the shaft 15 in the manner clearly shown at the left of Fig. V where they will idle upon the yshaft 15, their tops being a substantial distance below the tops of those sections which are in position upon the collar and which forni the gluing wheel.

For ready assembly and disassembly of the machine itis found convenient to providev the walls of` tank 1, the partitions 8 and the walls of the glue pot'5 with notches 33 whereby the shaft 15 may be let down into said notches to its mounting 16 in the walls of the tank 1 and may be readily lifted therefrom. For the same purpose it is found convenient to have the standards 19 bolted to the flanges 11 of the top 10 as at 34e, whereby the entire assembly of top- 10, shaft 15 and shaft 18 with their associate parts may be readily lifted o out of the machine and out ofthe tank, whereuponV the glue pot 5 may also be easily removed from the tank., y

It will be understood that the glue will be maintained inthe glue pot at a sufficient height to engage the lower portion of the gluing wheel composed of sections 32 mountthrough.

ed upon the collar 27 and it `will, also be understood that the water line in'tank 1 will be maintained .above the bottom of the glue pot but below the bottom` of the notches 33 so as to prevent leakage of water there- A carrier of any suitable construction, well understood by those familiar with the art, is

, provided and on account of such familiarity only a portion thereof has been shown, namely, the roller 35 which may be suitably mounted as byA lugs 36 on the tank 1 and pro-vided with grooves 37 for the accommodation of carrier cords 38 which cords, as will be understood, extend to and engage a roller similar to the roller 35 and spaced therefrom at any suitable distance for the purpose of permitting the glue on the carried covers to properly dry during the passage of the cover over the carrier as above referred to andas hereafter more fully described.

It will be understood also that a space is provided in the carrier between the carrier cords 38 and constituting a'continuation of the cut-away 14 in the top 10, this space being s provided for the glued strip on the cover during its passage over the carrier, that is'to say,

that the carrier cords .are so positioned as not to contact with kthe glued stip on the coverY while it is being carried by the carrier.V

n operationacover yfor a bookis placed upon the top 10 and against the slide 26 for proper positioning thereof to bring that portion of the cover which is to form the back of the book in alignment with the gluing wheel, it being yunderstood. that the outside of the cover is placed upward so'that the glue wheel will apply the glueto the inside of the cover. The cover is slid forward into the j aw formed betweenthe rollers21 and 13. The handle 2O is revolved causing 'revolution ofy shafts 13 and 15and likewise the revolution of the gluing wheel Vand the revolution of the rollers 21 and 13 willcausefthem to engage the edge of the coverand draw the same forward over the gluing wheel which will, in the process,

Y apply the glue to the cover in a strip at the f as to avoid contact of ythe roller .predetermined` prtionrthereof. The rollersVY 23 are providedy for `depressing theV central' portion of the cover for insuring' its engage-l ment'withthe gluing wheel andthe propery lThe number gluing wheel composing the. sameat the time of the operation'will obf viously determine thefwidth of the stripf application o-f the glue thereto. of sections 32 of the which is glued. The sections 32`which vdo not at thetime form a part of the gluing wheel will be out of ienwagementwith the cover by reason of their position on the shaft15, las clearly shown at Fig. V.

" It will be remembered that adjacent' and i beyond the gluing' wheel the top 10 is cut away as at 14 so that after the cover passes the gluing wheel and thence on to the carrier there will be nothing beneath the cover and opposite the glued strip to contact with the cover or the glue thereon, 1t beino' understood ness to hold the cover above and away from the roller 35. s

After the cover passes on to the carrier, it

is carriedthereby to a table or other suitable Lf place where an operator takes the cover from the carrier and inserts the book therein.

As previously stated, the lengthof the cary rier and the speed; thereof are arranged relatively to each other and to the consistency of the glue so that the length of time consumed 1n the passage of the cover from the gluing.

wheel to and over the carrier, through the air, will be sul'iicient and only sufficient to permit the drying of the glue on the cover' to the proper point vfor attachment thereto ofthek book. This relative adjustment of the length that the carriery cords 33 are of sufncient thicks and speed of the carrier and consistency of the glue can be readily determined and made, by thoseskilled in the art, atv the beginning of any given operation, and after such adjustment is made no further skill yan yunskilled operator may thereafter complete the. operation, kthe gluing and the proper drying of the glue being automatically provmanner hereinabove des is required and It will be obvious that the roller 35 maybe cut away at a point opposite cut-away 14. so 35 with the glued strip in case the cords 38 are so small in diameter as not to stand out above their grooves 37.

I claim:

In a machine forapplying adhesive material to sheets, a shaft'a hub carried by and of 130 greater diameter than the shaft and a gluing wheel, comprising sections adapted to be corelatively attached to form a wheel on said hub, of different widths predetermined ac- V5 cording to the number of sections thus attached, said sections being relatively detachable and adapted to be removed from said hub and to hang upon said shaft and out of operative position when detached.

In testimony whereof, I affix my signature.
